1. Copying the Engine Files

[Note] In this example, the engine file is extracted to the examples/bin/ directory to share it with other examples. However, for actual deployment, the engine file is typically copied to the directory where the application's executable file is located.

• For Windows x86 64-bit Extract the engine file to the examples/bin/windows-x86_64 directory

  7z x tsanpr*-windows-x86_64.7z

• For Windows x86 32-bit Extract the engine file to the examples/bin/windows-x86 directory

  7z x tsanpr*-windows-x86.7z

• For Linux x86 64-bit Extract the engine file to the examples/bin/linux-x86_64 directory

  tar xvf tsanpr*-linux-x86_64.tar.xz

• For Linux arm 64-bit Extract the engine file to the examples/bin/linux-aarch64 directory

  tar xvf tsanpr*-linux-aarch64.tar.xz

• Directory structure

2. How to Build

1. Native(JNI) Module

   • Windows 64bit (MSVC, x64 Native Tools Command Prompt)

     mkdir build\windows-x86_64
     cd build\windows-x86_64
     
     cmake ..\.. -A x64
     
     cmake --build . --config Debug   # Debug build
     cmake --build . --config Release # Release build

   • Windows 32bit (MSVC, x86 Native Tools Command Prompt)

     mkdir build\windows-x86
     cd build\windows-x86
     
     cmake ..\.. -A Win32
     
     cmake --build . --config Debug   # Debug build
     cmake --build . --config Release # Release build

   • Linux x86_64

     mkdir -p build/linux-x86_64
     cd build/linux-x86_64
     
     # Debug build
     cmake ../.. -DCMAKE_BUILD_TYPE=Debug
     make
     
     # Release build
     cmake ../.. -DCMAKE_BUILD_TYPE=Release
     make

   • Linux aarch64 (ARM64)

     • Build directly on the aarch64 machine

       mkdir -p build/linux-aarch64
       cd build/linux-aarch64
       
       # Debug build
       cmake ../.. -DCMAKE_BUILD_TYPE=Debug
       make
       
       # Release build
       cmake ../.. -DCMAKE_BUILD_TYPE=Release
       make

     • Cross-compile on x86_64

       mkdir build/linux-aarch64
       cd build/linux-aarch64
       
       # Debug build
       cmake ../.. -DCMAKE_TOOLCHAIN_FILE=../../toolchain-aarch64.cmake -DCMAKE_BUILD_TYPE=Debug
       make
       
       # Release build
       cmake ../.. -DCMAKE_TOOLCHAIN_FILE=../../toolchain-aarch64.cmake -DCMAKE_BUILD_TYPE=Release
       make

2. Java Module

   mvn clean package
